This study aimed to determine the pattern of cannabis and tobacco use among adolescent students in Sokoto and measure antinutritional factors in the two drugs. Qualitative and quantitative standard methods were applied. Reagents and materials of analytical grade were used to evaluate the antinutrients. Signs of drug abuse among adolescents are untidiness (33.3%), blackening of lips and toes (24.2%), poor concentration (20.0%), poor/foul odor (12.1%), false images (6.7%), hostility (5.5%), and reduced weight (1.2%). The perceived causes of drug abuse are peer pressure (36.4%), poor parental guidance (30.3%), labor/work (15.2%), learning musical art (9.1%), unemployment (6.1%)


Introduction
Education is a way of teaching formal knowledge to the recipient/s, delivered at schools or related institutions of learning.In education, students are trained to learn, read, and write, so they are institutionalized with a specialization that helps them acquire and perform the job effectively.Education makes a boy or girl with special training or learning to be able to earn a living in future life.Education is a tool that develops humans morally, mentally, socially, and emotionally to move out of poverty and become beneficial to society at large.Educated people are groomed with abilities, competencies, and training to work to move the economy forward.Therefore, education instigates social stability, mobilization, and proper socialization in the community and society [1][2][3][4][5].Every child, especially the adolescent, is essential in society.The adolescents are faced with several challenges ranging from poorly developed/developing body systems, the effect of poor pressure, experimentation, curiosity, a strong urge for independence, and poor life experiences.Therefore, require effective education to socialize and become valuable members of society.However, a significant threat to education and adolescents nowadays in many parts of the world, including Sokoto state, is rising substance abuse prevalence [6][7][8][9].
Substance abuse is regarded in many terms.It is a behavior of taking drugs in a fashion that leads to impairment of body functioning or a visible failure at school, home, or any place of work [10].Substance abuse, on many occasions, has to do with youngsters taking drugs/ psychoactive chemicals without legitimate cause or prescription/ medical indication [6].The menace of drug abuse among adolescents has been on the rise worldwide, with many of them consuming multiple substances for various reasons, leading to diverse effects on the users and society.Factors such as peer pressure, poor parental guidance, labor, experimentation, personality, family issues, academic problems, and others are among the identified factors linked with adolescent drug abuse nowadays [6,11].
Indeed, adolescent drug abuse affects education negatively in many ways.Adolescents who engage in drug abuse, let alone the use of cigarettes and cannabis, are faced with poor relationships with peers and staff at school, academic difficulty, the tendency for risky behaviors, illnesses, violence, diseases, psychological distress, and other physical effects.Therefore, unhealthy adolescents tend to be hospitalized or have to avoid school/ class for treatment, which affects their education or academic performance.Conversely, adolescent drug users tend to have psychological instability that affects learning through several pathways [12][13].Nevertheless, the effects manifesting due to cigarettes or cannabis, or any drug of abuse in adolescents are due to the chemical constituents of the drug thereof.Because tobacco and cannabis are of plant origins and due to pollution, they have tendencies to contain antinutritional factors that adversely affect humans, let alone adolescents [13].
However, antinutrients present in plant-based products such as cannabis and tobacco are made initially to serve as protection for the plants against microbial attack, parasitic attack, herbivore attack, and relations [14][15][16][17].Intake of cannabis and tobacco is an intake of these toxins (antinutrients).In turn, they can build up in the body and impede the intake, digestion, absorption, and utilization of helpful food nutrients [17].Parable oxalate affects calcium and magnesium metabolism and also inhibits pectin digestion.It also affects the kidney by forming insoluble salts that form stones [17].Phytate makes essential elements inaccessible by making compounds that reduce absorption and digestion in the intestine.Alkaloids act on the nervous system and disrupt the standard transmission of impulses.Cyanide or its relations form hydrogen cyanide that, in turn, inhibits the cytochrome oxidase and other valuable enzymes.Tannins bind proteins, forming complexes due to their phenolic groups and decreasing food intake, growth, and digestion [16][17][18].In this vein, adolescence is a pivotal period of human life that is known for the fastest physical, sexual, psychosocial, cognitive, and related development; therefore, an adolescent needs better and proper nutrition to achieve potential and goals [16][17].Therefore, the intake of cannabis and tobacco laced with antinutrients could harm the health, education, and other aspects of youngsters and the nation's economy [19].This study aimed to determine the pattern of cannabis and tobacco use among adolescent students in Sokoto and measure antinutritional factors in the two drugs, as shown in Figure 1.

Method
The study was carried out in Sokoto State, Nigeria.The map of the area is denoted in Figure 2. The respondents' information pertaining to this work was collected through a semi-structured questionnaire with subsections.Section A asked about the demographics, section B asked about the use of the drugs, section C asked about the signs of drug abuse among adolescents, section D asked about the effects and possible causes of drugs, and Section E asked about possible prevention of drugs in adolescents.The sample size was 330, calculated using a Raosoft calculator, and the obtained questionnaires were analyzed using descriptive statistics to give frequency and percentage; in addition to that, the  2 was used to test the results  < 0.05.Tobacco and Cannabis were collected from Sokoto City, Nigeria.The alkaloids, oxalate, cyanide, tannins, and phytate were determined as reported in the standard procedure mentioned in [20].

The levels of antinutrients in cannabis and cigarette collected in Sokoto
Various concentrations of antinutritional factors present in some tobacco and cannabis collected from Sokoto are shown in Table 1.Therein, tobacco contains more of the observed antinutrients than cannabis, an observation that might be due to pollution from the environment utilized in growing the crop and pollution that might have occurred along the course of production or processing of the drug [19,[21][22].In addition to that, tobacco contains much cyanide (38.0±1.3 mg/100g), followed by phytate (35.0± 0.15 mg/100g), then alkaloids (25.0±0.5 mg/g).Others are Oxalate (20.0±2.1 mg/100g) and tannins (18.2±1.6 mg/100g).Cannabis contains more cyanide (28.0±2.1 mg/100g), Oxalate (16.0±1.0 mg/100g), followed by phytate (15.0±0.05mg/100g).Other constituents are Alkaloids (13.0±1.3 mg/100g) and tannins (10.2±1.0 mg/100g).Notably, the antinutrient content of the drugs (cannabis and tobacco) is higher than the levels of phytate, Oxalate, and alkaloids found in vegetables in Bauchi, Nigeria [23].The results also contribute to the phytate, tannins, and oxalate levels determined in cereals (maize and rice) from Sokoto [24].Moreover, the tannins, phytate, alkaloids, and Oxalate found in this work are comparatively higher than those observed in Moringa collected in Sokoto [18].Impliedly, the two drugs of abuse might be more likely to contain antinutrients than other vegetables and other edible plants.Usually, plants are in the habit of innovating protection strategies against invading microbes (parasites) and attacks by predators.Therefore, they manufacture antinutrients as protective measures [25][26].Nevertheless, the consumption of cannabis and tobacco observed in this study by adolescents is coupled with the consumption of antinutrients found (Table 1) therein.Therefore, the behavior is dangerous to health and learning because the antinutrients hinder digestion, absorption, bioavailability, and utilization of valuable food materials adolescents consume.
The behavior leads to deficiencies, malnutrition, disorders, and poor health [27].Unhealthy, malnourished individuals abstain from classes/ schools (for health seeking), affecting their performance.Even if they attend classes, they usually perform poorly because proper food is essential for growth, development, and learning [28,[7][8][9].Specifically, phytate naturally occurs in plants and can be complex with positively charged valuable minerals like iron, zinc, phosphorus, and other micronutrients needed for development and growth.Tannin compounds bind and cause the precipitation of proteins and other beneficial organic compounds like proteins.They can also interfere with iron metabolism [29].Oxalate can lead to kidney stones and other consequences [26][27].Alkaloids at higher concentrations spur anticholinergic poisoning.A range of 11-25mg/kg can lead to death in children [27].They also can elicit hallucinations, stimulation, induction, and infertility.
Otherwise, cyanide can affect nutrients such as iodine, which are essential in youngsters' growth and development and learning ability [29][30].It is worth stating that the presence of antinutrients in the two drugs is excellent potential to affect the education of the adolescents taking cannabis and tobacco in Sokoto by causing malnutrition, deficiencies, ill-health, school absenteeism, and poor cognitive ability [31][32].Care needs to be taken to educate the public (especially the youth) on the harmful nature of drug use, and strict law implementation is needed to scuttle the selling and buying of drugs in question [10].

The distribution of cannabis and cigarette use among adolescent students in Sokoto
The distribution of cannabis and cigarette use among adolescent students in Sokoto, Nigeria, is shown in Table 2.The most used drug was tobacco (50.0%), followed by cannabis (33.3%) and a combination of drugs (16.7%).Substance abuse refers to using a drug or any psychoactive substance in a harmful manner or without the prescribed need [7][8][9].The types of drugs used by adolescents found in this study (Table 3) were similar to what was reported by another Sokoto study.In another streak, Aliyu et al. (2016) reported the practice of smoking (cigarette and relations) among youths in the North-Central zone of Nigeria.They echoed that smoking was a recipe for other drugs/ psychoactive substances use among youth.It has spurred youths to use even non-conventional substances such as moringa, zakami, rubber solution, premium motor spirit, lizard dung, and others [33].Another study related a high prevalence of substance abuse among youth in Nasarawa, a Northern state similar to Sokoto in many aspects [11].

Signs and features of cannabis/ cigarette abuse among adolescents in Sokoto
The possible signs and features of cannabis or cigarette abuse among adolescents are shown in Table 3.The most stated sign was untidiness (33.3%), followed by blackening of lips and toes (24.2%), then poor concentration (20.0%), and poor body odor (12.1%).Others are false images (6.7%), hostility (5.5%), and reduced weight (1.2%).Invariably, these signs were reported elsewhere [10] and are essential portends that help parents and caregivers or any stakeholder to prevent drug abuse in adolescents at early stages before escalation or deterioration occurs [7][8][9].

The perceived possible causes of cannabis and cigarette abuse among adolescents in Sokoto
The perceived possible causes of cannabis and tobacco abuse among adolescents in Sokoto, Nigeria, are shown in Table 4.The causes are enumerated in the order of frequency as follows: Peer pressure (36.4%),Poor parental guidance (30.3%),Labour/ work (15.2%),Learning musical art (9.1%), Unemployment (6.1%), and Sports (3.0%).Indeed, substance abuse is caused, associated with, and linked to many factors, especially among youths which need to be expunged for better prevention of the prevalence of the menace.Similar to the findings of this study (Table 4), peer pressure was also a highly prevalent factor of drug abuse among youths, as related by [11] in Nasarawa, Nigeria.Peer pressure was also related as a determinant of drug abuse among undergraduates in Southeastern Nigeria [34].A study has revealed that people who are friends with drug abusers are more prone to indulge in the act than their counterparts [11].Other causes of drug abuse are diverse [34].

Experienced effects of cannabis or cigarette abuse among adolescents in Sokoto, Nigeria
The outcome shown in Table 5, the possible effects seen by the adolescents linked to cannabis and tobacco revealed, Health effects (27.3%), followed by Poor academic performance (24.2%), then confusion (21.2%), school dropout (16.9%), disrespect (7.3%), and lastly disrespect (3.0%).A surf of literature has revealed that substance abuse also negatively affects users and non-users.Similar to this work, physical effects were reported elsewhere (Table 5).They involve illness or signs such as coughing, dizziness, weight loss, unperturbed sleeping, weakness, sickness, and withdrawal, as reported in a Sokoto study [8].Other effects are on the social and psychological well-being of the users, such as mood alteration, low sexual desire, poor relationship with others, well-being, misbehaviors, and others, found by [8][9].[33] reported similar effects to this finding (Table 5), such as hospitalization and injuries.

The suggestions for prevention of cannabis and cigarette abuse among adolescents in Sokoto
The possible ways to prevent cannabis and cigarette abuse among adolescents in Sokoto, Nigeria, as suggested by the respondents, are shown in Table 6.
The suggestions are in descending order of frequency as enumerated below: Strict restriction on drugs (33.3%),Education/ awareness about the effects of drug abuse (26.7%),Religious intervention (21.2%),Avoiding bad peers (9.7%), and Proper parental guiding (9.1%).[33] echoed for more educational and awareness approaches, family interventions, and drug laws interventions to help prevent drug abuse among youths in the Northern part of Nigeria, similar to some suggestions offered in this work (as indicated in Table 6).In this vein, [11] suggested public awareness enhancement, public health interventions, and constant education of parents to their wards on the negative effects of drugs.
Likewise, another study elsewhere hinted at the influence of religion on reducing drug abuse.Therefore, using religious leaders to preach on the spiritual consequences and toils for the drug users would invariably help in deterring many from drugs/ psychoactive substances at school, home, or elsewhere [35].In a nutshell, the findings of this study show that adolescents and students are still practicing the practice of drug abuse, and the antinutritional contents of the drugs can severely affect the health, education, and nutrition of consumers with outward consequences.Religious measures help prevent the trend, and parents are expected to pay much attention to their wards regarding substance abuse.Likewise, governments should properly implement drug control and prevention policies because promising youngsters are needed for the growth and development of the entire nation.

Conclusion
Substance abuse is a menace among the studied adolescents, and antinutrients present in the drugs affect the users, especially their academic performance.This study revealed that adolescent students in Sokoto take cannabis and tobacco drugs and show some signs due to the action.Likewise, there are possible ways to prevent the habit of drug abuse.However, the two examined drugs contain antinutrients (oxalate, phytate, tannin, alkaloid, cyanide) that are in significant amounts and, in turn, can affect the health, education, and development of the users by eliciting malnutrition, deficiencies, and other nutrition-related abnormalities.Therefore, drug abuse should be controlled by implementing strict policies that prevent selling and buying; parents should give proper care, and religious interventions are needed, among others.
